Abstract: An electromotorically driven pump (1) includes control electronics (6) for the connection of at least one sensor (5). The control electronics (6) are configured to detect values of an output signal (9) of the connected sensor (5) continuously or in temporal intervals, and after completion of a predefined time, to automatically set a measurement range of the sensor (5) based on the detected values.

Abstract: An electronic converter unit (30, 86, 87) for being arranged external to a pump unit (10) is described. The pump unit (10) includes a housing (12), which comprises a signal source (16, 18) for emitting a signal. The electronic converter unit (30, 86, 87) comprises a signal detector (40) for measuring the signal emitted from the signal source (18) of the pump unit (10). The electronic converter unit (30) further comprises a converter unit (41) for converting said signals to electrical signals, and transmitting means (42) for transmitting the electrical signals to an external communication unit (50). The electronic converter unit (30, 86, 87) is further configured to operate in a signal converter mode (30) and a signal repeater mode (86, 87).
